When & Where 

Lived during the Middle Jurassic 170 to 160 million years ago.

Cetiosaurus was first discovered in 1842 and it was the first sauropod to be described. Almost a complete skeleton was found in England. It was described and given a name in 1871. It is assumed that they lived in terrestrial habitats dependent on the natural flora. Some believe that they could live on floodplains and open woodlands. 

Size & Weight

Cetiosaurus was a large sauropod for its era, but compared to other sauropods through all time it was only medium size. It could stretch to around 50’ (16 meters) in length and around 10’ (3 meters) in height measured at its hips, weighing in at around 22.000 lbs (10.000 kg).

Mobility & Diet

Their main diet was based on plants. It used to feast on trees that were out of reach to its fellow plant-eaters.  

Interesting Points
